POSSESSION || J.JK FF || Mafia Au

Y/N was never meant to see it.
One wrong turn. One wrong moment.
And she witnesses something she was never supposed to survive -
The heir of a respected business empire.
The perfect family.
The lie.
She should have been silenced.
Instead, she is taken.
Hidden inside the very house she now fears. Watched. Guarded. Kept close - not out of affection, but necessity.
And then comes the marriage.
Not romantic. Not arranged.
But strategic in the darkest way possible.
To protect the family name.
To protect the underground empire no one knows exists.
To make sure she never speaks.
Jungkook tells himself it's control. Containment. A solution.
But living under the same roof changes things.
She sees the cracks in his composure.
He sees the strength in her fear.
The world still believes he is nothing more than the heir to a powerful businessman.
They don't know he runs the underground mafia his father built.
They don't know that the girl who witnessed everything now sleeps in his house.
And when enemies begin to circle and blood stains marble floors, Jungkook realizes too late-
Keeping her close might have saved his secret.
But it may cost him his heart.
Did he possess her to protect his secret...
Or has she slowly taken possession of his heart?
